The invention discloses an earth wire communication method and an earth wire communication system. The earth wire communication method comprises the following steps of detecting a magnetoelectric property environmental parameter when a current earth wire channel is in idling time; adjusting a static magnetoelectric property environmental parameter of a signal transmission output end to be matched with the magnetoelectric property environmental parameter when the earth wire channel is in idling time; outputting a basic correction signal adapted to the magnetoelectric property environmental parameter of the current earth wire channel according to the magnetoelectric property environmental parameter of the current earth wire channel; and timely adjusting a signal format and a signal transmission structure of an earth wire conductor according to an attenuation degree and a transmission signal-to-noise ratio of the signal of a receiving end. According to the method, by designing the signal transmission structure of an earth wire earth conductor adapted to the magnetoelectric property environmental parameter when the earth wire channel is in idling time and the signal format having small influence on a signal transmission distance, attenuation of the earth wire communication signal is small, the good communication signal is achieved, and the transmission signal-to-noise ratio of the signal is improved by using the property that no parasitic electromagnetic interference exists between the earth wire earth conductor and the earth, and the anti-electromagnetic interference performance of the signal is enhanced.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a ground line communication method and system. Background technique [0002] In underground space operations, the stability and reliability of wireless signals are limited by the environment. However, wired communication cables are easily damaged in geological disasters, so that the emergency communication of geological accidents in underground operations has not been effectively resolved. At the same time, in industrial monitoring communication, the control signal line is often accidentally grounded, which affects the transmission of the signal. Emergency communication is very important in fires, collapses, and water damages that damage conductors. Contents of the invention [0003] In view of the above-mentioned deficiencies existing in the current underground communication, the present invention provides a ground wire communication method and system, which ha...
